Mixing machine system

A mixing machine, comprising:

• a head extending over a bowl receiving location, the head including a downwardly extending rotatable output shaft for receiving a mixer tool;
• a drive train including a motor having an output operatively connected to drive a planetary gear system, where the planetary gear system effects rotation of the rotatable output shaft about its axis and orbiting of the shaft axis about another axis;
• a user interface;
• a control system including:
• a master control unit connected with a first sensor located along the drive train between the motor and the planetary gear system, the master control unit also connected to the user interface;
• a slave control unit connected with a second sensor, wherein both the slave control unit and the second sensor rotate with a part of the planetary gear system, wherein the master control unit and the slave control unit are configured for wireless communication with each other.
